[0002] Photovoltaic modules are one of the important components of solar power generation systems, which are used to convert solar energy into electrical energy. Photovoltaic modules are usually composed of components such as solar cells, external brackets, glass covering layers and back panels. Existing photovoltaic modules are composed of solar panels and bracket systems. When solar panels are exposed to the outside for a long time, a certain amount of dust will adhere to their surface, which will affect the panels' absorption of solar energy and need to be cleaned by a cleaning device.

The jet assembly is connected to a three-way pipe through a bearing rotation. The airflow is injected into the three-way pipe by a fan, and the airflow will pass through the three-way pipe and the jet assembly.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1-Figure 3 The utility model provides an embodiment of a new energy photovoltaic heat dissipation and dust removal structure, comprising two groups of support frames 1, the outer side wall of the left support frame 1 is fixedly connected to a motor 2, the inner wall of the support frame 1 is rotatably connected to a reciprocating screw rod 3, the output shaft of the motor 2 is fixedly connected to the rotation center axis of the reciprocating screw rod 3, the sliding seat 4 is threadedly connected to the surface of the reciprocating screw rod 3, the reciprocating screw rod 3 is a prior art, and its surface is provided with two groups of positive and negative threads, which are controlled by the motor 2 to rotate, thereby driving the sliding seat 4 to reciprocate on the inner wall of the support frame 1, the outer side wall of the water storage pipe 51 is fixedly connected to an external water pipe 53, and the cleaning liquid can be replenished in the water storage pipe 51 at any time through the external water pipe 53, the inner wall of the two groups of support frames 1 is slidably connected to the sliding seat 4, two groups of sliding seats 4 are set so that one group controls it to reciprocate, and the other group guides the rising position of the cleaning roller A62, thereby preventing the sliding seat 4 from rotating with the reciprocating screw rod 3.

[0034] Reference Figure 1-Figure 3 The outer side wall of the support frame 1 is fixedly connected with a fixing seat 8, and the bottom end of the outer wall of the fixing seat 8 is fixedly connected with a guide rod 9. The inner wall of the fixing seat 8 is threadedly connected with a threaded rod 10. A handle is provided at the top of the threaded rod 10, and the threaded rod 10 can be rotated by the handle to rotate, thereby driving the clamping plate 11 to rise, and cooperate with the corresponding bottom end of the support frame 1 to fix the whole on the surface of the photovoltaic panel. The bottom end of the outer wall of the threaded rod 10 is rotatably connected with a clamping plate 11, and the clamping plate 11 penetrates and is slidably connected to the surface of the guide rod 9. An empty groove is opened on the surface of the clamping plate 11, so that the clamping plate 11 can move up and down on the surface of the guide rod 9, thereby guiding the rising position of the clamping plate 11, thereby preventing it from rotating during the rising process. The top of the outer wall of the two groups of support frames 1 is provided with a spray assembly 5.

[0035] Reference Figure 3 and Figure 6 The spray assembly 5 includes a water storage pipe 51, and a cavity is arranged inside the water storage pipe 51. The cleaning liquid can be added to the inside of the water storage pipe 51 through an external water pipe 53. One end of the water storage pipe 51 is fixedly connected to the top of the outer wall of the right support frame 1, and the other end of the water storage pipe 51 is slidably connected to the top of the outer wall of the left support frame 1. A slide groove is provided at the bottom end of the water storage pipe 51, so that when the cleaning roller A62 and the cleaning roller B63 are away from each other, one end of the water storage pipe 51 will move laterally on the surface of the left support frame 1. A plurality of groups of nozzles 52 are arranged on the surface of the water storage pipe 51, and the water storage pipe 51 is sprayed outward from the nozzle 52 through the plurality of nozzles 52, and the nozzle 52 is provided with a plurality of nozzles 52. The valve is a prior art. The outer wall of the water storage pipe 51 is elastically connected to the contact block 54 through a limit spring 55. One end of the limit spring 55 is fixedly connected to the inner side wall of the contact block 54, and the other end of the limit spring 55 is fixedly connected to the outer wall of the water storage pipe 51. The function of the limit spring 55 is to automatically reset the position of the contact block 54 after being squeezed and moved. The outer side wall of the sliding seat 4 contacts the outer wall of the contact block 54. The contact between the two causes the sliding seat 4 to squeeze the contact block 54 to drive the wedge block 56 to move, thereby squeezing the moving block 57 to drive the piston 58 to move inside the water storage pipe 51, so that the nozzle 52 sprays the cleaning liquid outward.

[0036] Reference Figure 5-Figure 6 The bottom end of the outer wall of the contact block 54 is fixedly connected with a wedge block 56, and the wedge block 56 is slidably connected to the inner wall of the water storage pipe 51. The bottom end of the outer wall of the wedge block 56 is slidably connected to the inner wall of the guide groove at the top of the moving block 57. The front end of the wedge block 56 is provided with a protrusion that fits the guide groove of the moving block 57, so that the wedge block 56 can only move on its inner wall and cannot be separated from its inner wall. The inner wall of the water storage pipe 51 is slidably connected with a piston 58, and the piston 58 moves on the inner wall of the water storage pipe 51, thereby squeezing the internal space, so that the cleaning liquid is sprayed out from the nozzle 52. The left outer wall of the piston 58 is fixedly connected with the moving block 57, and the outer wall of the sliding seat 4 is provided with a cleaning component 6.

[0037] Reference Figure 1 and Figure 2The cleaning component 6 includes a cleaning roller A62, the inner wall of which is slidably connected to a cleaning roller B63. Cleaning brushes are provided on the surfaces of the cleaning rollers A62 and B63, so that dust on the surface of the photovoltaic panel can be cleaned. At the same time, the cleaning roller B63 moves on the inner wall of the cleaning roller A62, so that photovoltaic panels of different sizes can be cleaned. The cleaning roller A62 is rotatably connected to the outer wall of the sliding seat 4, and the cleaning roller B63 is rotatably connected to the outer wall of the right sliding seat 4. The surface of the cleaning roller A62 is fixedly connected to a gear 61, and the top of the outer wall of the left support frame 1 is fixedly connected to multiple groups of racks 7. The gear 61 is meshed with the rack 7. The meshing between the two allows the sliding seat 4 to move, which will drive the gear 61 to rotate, thereby meshing the rack 7 to rotate the cleaning roller A62 and the cleaning roller B63, so as to clean the dust on the surface of the photovoltaic panel.

[0038] Working principle: When cleaning the photovoltaic panel, the two sets of cleaning rollers A62 and cleaning rollers B63 can be expanded outward synchronously, so that the cleaning rollers B63 can move on the inner wall of the cleaning rollers A62, so that the two sets of support frames 1 are attached to both sides of the surface of the photovoltaic panel. At this time, the threaded rod 10 can be rotated to move on the inner wall of the fixed seat 8, so that the clamping plate 11 can rise with it, thereby cooperating with the support frame 1 to clamp and fix the two sides of the photovoltaic panel.

[0039] At this time, the cleaning liquid can be added to the inside of the water storage pipe 51 through the external water pipe 53, and the motor 2 is started to make its output shaft drive the reciprocating screw 3 to rotate, so that the sliding seat 4 moves on the inner wall of the support frame 1. During the movement of the sliding seat 4, it will drive the cleaning roller A62 and the cleaning roller B63 to move, and the gear 61 on the surface of the cleaning roller A62 will engage the rack 7, thereby driving the cleaning roller A62 and the cleaning roller B63 to rotate, so as to clean the surface of the photovoltaic panel. At the same time, when the sliding seat 4 moves to the top of the inner wall of the support frame 1, its outer wall will squeeze the contact block 54, so that it drives the wedge block 56 to move on the inner wall of the water storage pipe 51, and The limit spring 55 is elastically compressed. At the same time, when the wedge block 56 moves, it will move in the guide groove of the movable block 57 and squeeze its inclined surface to allow the piston 58 to move on the inner wall of the water storage pipe 51, so that the internal cleaning liquid can be sprayed from the nozzle 52 to the surface of the photovoltaic panel to reduce dust and cool the photovoltaic panel. Until the sliding seat 4 cancels the squeezing of the contact block 54, the contact block 54 will be elastically acted upon by the limit spring 55, and it and the wedge block 56 will be synchronously restored to the initial position, thereby driving the movable block 57 to synchronously restore to the initial position, so that the piston 58 is restored to the initial position, so that the valve of the nozzle 52 stops opening to stop spraying water.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
